Probing the mysterious second-wave of damage in head injury patients

28.10.2010
Why do some of the one million people who sustain head injuries annually in United States experience a mysterious second wave of brain damage days after the initial injury — just when they appear to be recovering?

Limited clinical trials using an innovative new device to monitor brain chemistry on a second-by-second basis are underway to answer that life-and-death question, according to an article in the current issue of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine. Brain injury is the leading cause of death and disability worldwide.

C&EN Senior Editor Celia Henry Arnaud describes a phenomenon called depolarization, in which brain activity decreases in patients following initial trauma. The condition involves a wave of chemical changes that spread from the site of injury and inactivate nerve cells.

Since reactivation of these cells requires large amounts of glucose, monitoring glucose levels in a patient's brain can help doctors tell whether or not a patient is taking a turn for the worse. The article points out that a promising new device could provide a faster and more useful way to monitor brain glucose than current methods, which are inefficient.

Now in development at Imperial College London, the new so-called "microfluidic method" measures glucose quickly and continuously — in fractions of a second instead of hourly.

The device is currently being tested in patients who have suffered trauma, stroke, or aneurysm (a balloon-like enlargement of a brain artery). In the future, the device could be used in patients with milder forms of brain injury and used in a way that is less invasive, the article notes.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
